Abstract

Purpose: To verify the effect of sitting posture with and without sole-ground contact on chewing stability and masticatory performance.

Methods: Thirty healthy subjects were evaluated. The Conformat was used to analyze the center of sitting pressure (COSP), and the three-dimensional motion analysis system was used to analyze changes in head and trunk postures while subjects remained in a sitting position with and without sole-ground contact. The parameters of masticatory performance and movement were calculated as follows. For evaluating masticatory performance, the amount of glucose extraction (AGE) during chewing of a gummy jelly was measured. For evaluating masticatory movements, the movement of the mandibular incisal point was recorded using the Motion Visi-Trainer V1, and parameters of the stabilities of movement path and rhythm were calculated.

Results: Head and trunk sway values and the displacement of COSP were significantly smaller with sole-ground contact than those without sole-ground contact. The masticatory movement path with sole-ground contact showed less variation in the opening distance and more stable movement path compared to those without sole-ground contact. The AGE was significantly greater with sole-ground contact than that without sole-ground contact.

Conclusion: Sitting posture with and without sole-ground contact affects chewing stability and masticatory performance.

有和无足底地面接触的坐姿对咀嚼稳定性和咀嚼性能的影响。
目的:验证有或无足底地面接触的坐姿对咀嚼稳定性和咀嚼性能的影响。方法:对30名健康受试者进行评估。Conformat用于分析坐姿压力中心(COSP),三维运动分析系统用于分析受试者在有和没有单独地面接触的情况下保持坐姿时头部和躯干姿势的变化。咀嚼性能和运动的参数计算如下。为了评估咀嚼性能,测量了口香糖咀嚼过程中的葡萄糖提取量(AGE)。为了评估咀嚼运动,使用Motion Visi Trainer V1记录下颌切点的运动,并计算运动路径和节奏的稳定性参数。结果:有单独地面接触时,COSP的头部和躯干摆动值和位移明显小于没有单独地面接触的COSP。与没有鞋底地面接触的咀嚼运动路径相比,鞋底地面接触时的咀嚼运动轨迹显示出较小的张开距离变化和更稳定的运动路径。有单独地面接触时的AGE明显大于没有单独地面接触的AGE。结论:有或无足底地面接触的坐姿影响咀嚼稳定性和咀嚼性能。
